Here are some pics of the progress I had recently with the Wizard Arena.
The circle cut areas are intended for insert pieces; some of those are pictured below (as yet unpainted).
The hexagulon tiles are from Aba and Keebs at KeeblerStudios.com
The arch pieces are from the A&K "Moria" mold, one of my favourites.
Check out A&K molds at KeeblerStudios.com (link over there <--).
